separation of the insei-tion of opposite legs, and the form of the metaster- 

 num. 



Tlie insect must have been of about the size of the common T. molitor. 

 Head well rounded, shaped, so far as can be seen, exactly as in T. molitor, 

 the surface uniformly more finely, more densely, and perhaps not quite so 

 deeply punctate. Fore and middle coxte attingentor subattingent when the 

 prothorax is bent down, the middle pair separated from each other by about 

 half the middle length of the metasternum ; the metasternum is shaped 

 in general as in T. molitor, but is relatively shorter, and the anterior 

 mesial lobe, which separates the middle coxte, is much broader and shorter, 

 and its front border is slightly emarginate ; as in T. molitor there is a 

 median sulcus, deepest posteriorly, but the surface sculpture is very dif- 

 ferent, being coarsely and profusely punctate, coarsest and more separated 

 on the anterior mesial lobe, more or less confluent, transversely, next the 

 rest of the anterior margin. The femora are much shorter and stouter 

 than in T. molitor, rather coarsely punctate, the tibije far stouter, resem- 

 bling the femora and similarly punctate. The elytra are punctate exactly 

 like the head, with sharply incised, fine, but by no means deep strict, 

 which become evanescent toward the tip. 



Width of metasternum, 4-9""" ; length of same, 1-25""" ; length of 

 hind femora, 2-25'""\ 



Tenebrio molitor occurs in North America from Nova Scotia to Mexico, 

 and is also found in Alaska. It is a European insect.*

A pair of rather poorly preserved elytra, parted at the tip and showing 

 between and through them the outlines of the abdominal segments, repre- 

 sents a species of Chrysomelid;ie, which appears to be most nearly allied to 

 the genus in which I have placed it, and to \)e about the form of, and a 

 little smaller than, O. maritima LeC. The elytra are uniformly piceous 

 throughout, showing no marks of lighter coloured borders ; there are faint
